Modifying old RSS script to also handle Atom

PHP
1

My site uses an old script that is no longer supported by its author - it also hasn’t been updated since 2006…

The script works well… but it seems to trip up when processing ATOM feeds… basically it can’t handle them.

Is there any kludge or minor bit of code revision that could be introduced in to this script to enable it to handle ATOM ( as well as keep its current functionality with RSS )

					$two= strtolower(str_replace(' ', '', $string));
					$res = count(count_chars($two, 1));
					return $res;
